format (or temporal_format_property) is not taken into account with result()

[cschloer]

Running a pipeline with a Date field looking like:

          {
            "name": "Date",
            "type": "date",
            "outputFormat": "%Y-%m-%d",
            "format": "default"
          }

returns a string looking like 2018-07-30T00:00:00

The same thing actually happens with

          {
            "name": "Date",
            "type": "date",
            "format": "%Y-%m-%d"
          }

which is weird because it's not even returning a string that looks like a Date (rather a Datetime).

It would be important to add

1. The format is reflected in the return values of results()
2. The ability to input a temporal_format_property to the results function.

Ignore this issue - my fault. Issue with celery converting datetime to string on my end.
